- SHEET-METAL can.

Specification of Letters Yatent.

Application filed August 7,- 1914. Serial No. 855,613.

T all whom it may concern Be it known that I, CHARLES S. HARDY,

' a citizen of the United States, and'a resident of San Diego, in the county of San-Diego and State .of California, have-invented an Improvement in Sheet-Metal Cans, of which the following is a specification.

My present invention relates generally to sheet metal cans, and more particularly to. a sheet metal can or pail, the body of which is provided with a rolled finished upper edge for the reception of the usual slip cover in order that the can or pail may be used continuously and for various purposes after its original contents have been removed, my ob ject being to provide an extension top for the can body of such a nature that the original contents ofthe can may be hermetically sealed, said extension top being'adaptedto receive the ordinary slip cover and being separable fromthe can body in such a manner as to leave the finished rolled upper edge of thebod'y free and unbroken for the reception of the cover in its after use. I preferably accomplish these objects by means of an extension topapplicable to ,a

' can body having a finished rolled upper edge and having a rim portion scored circumferentially to form a rip stripwhich is in the 80 first instance soldered to the said finished rolled edge of the can body, the said extension top being adapted to telescopingly receive the usual slip cover which, upon removal of the supplemental top by means 5 of the rip. strip, may be thereafter readily associated with the finished rolled edge of the can body in the usual manner.

- In the accompanying drawing, which illustrates my invention, Figure 1 is an ele- 40 vation of a can or pail constructed in accordance with my invention, with the supplemental top in position to hermetically seal the can body and with'the usual slip cover shown in. dotted lines. Fig. 2 is a similar view of the upper portion of the can illustrating the supplemental top partially removed. Fig. 3 is avertical section through the upper portion of the hermetically sealed can as shown in Fig. 1. Fig. 4

i is a similar view with the. slip cover disposed thereon and as the can or pail is sold with its original contents, and Fig. 5 is another similar view showing the cm or associated with the upper finished edge of the can body 5 in use after the supplemental top hasbeens rem'oued and the original contents. of the can or pail exhausted and constituting a slight modification as regards Fig. 3.

Referringnow' to these figures I have shown at a can body or pail, for instance for the transportation and sale of lard and commodities of this nature and which is provided with a finished rolled upper edge A as clearly seen in Figs. 3 to 5 inclusive, and a circumferentlal bead A below this Patented Nov. 9, 1915.

edge, adapting the can or pail body A to edge A of the body A- and is secured there to in air-tight relation by solder. This rim B ofthe supplemental top is intermediately and annularly scored at B whereby its lower edge which is secured to the can body in the manner just described constitutes a rip strip B, said rip strip having an eXten-.

sion 13 at one end for engagement by the usual rip strip key C as seen in Figs. 1, 2 and 3. In this connection it will be noted particularly from Fig. 4 that the rim B of the supplemental top tapers inwardly and upwardly and that the outer edge of the rolled joint 13 between its plate B and the rim B is preferably in substantially thesame'vertical plane with the outer peripheral face of the rolled body edge A, thus adapting the supplemental top B to receive the usual slip cover D in the mannerbest shown in Figs. 4 and 5 and which cover is adapted to be associated either with the finished rolled edge A of the body A, as seen in Fig. 5', or with its bead'A the body edge A being in both cases left unbroken upon the removal of-thesupplemental top B by ripping off the strip B in the usual manner, in order that the can or pail body with the slip cover D may be thereafter and following. the removal of the original contents thereof, utilized for various purposes as'may be desired. The same result may be accomplished in Fig. 3, where the slip cover will engage the circumferential bead A when the supplemental top B is removed. Thus by the use of my invention, a soldered connection with the finished rolled edge of a can body is ripped to re a part of such supplemental top and being formed by circumferentially scoring the latter, the said supplemental top itself consistingof a flanged rim and a top plate, the former of'which is first solderedjaround the can body and the latter of which is then joined to the flange in such a manner as to hermetically seal the can body.

It will be understood that Where cover '3 is rolled on to extension B that cover B will be provided with a suitable cement similar to that used in the ordinary sanitary can, which together with the rolling of cover B 'makes a hermetically sealed joint.

I claim:

The combination of a can body having a finished upper edge, a'slip cover for the can body adapted to be associated with the said finishededge thereof, and a supple-- mental top forhermetically sealing the body including a rim having. a flanged upper edge lower. edge, the said rip strip being telescopingly disposed upon and having a soldered connection with, the finished edge of the ean body, and a top plate having a rolled and soldered or cemented connection With the flanged upper edge of the rim and adapted to receive the .slip cover in telescoping relation.- v
